Class ImmutableDateMotionCollection2<T,TDerivative>

java.lang.Object

agi.foundation.ImmutableDateMotionCollection2<T,TDerivative>

Type Parameters:

T - The coordinate type that this collection contains. Values (get) will be collection of this type.

TDerivative - The derivative type that this collection contains. FirstDerivatives (get), SecondDerivatives (get), and additional derivatives are lists of this type.

public class ImmutableDateMotionCollection2<T,TDerivative>
extends Object

A collection of Motion2, each of which is associated with a particular JulianDate. This is a convenient and efficient way to store time-varying position and velocity, etc. Each Motion2 instance is required to have the same Order (get).

Method Summary

Modifier and Type	Method and Description
List<TDerivative>	get(int index) Gets the list of the specified derivative.
int	getCount() Gets the number of items in this collection.
List<JulianDate>	getDates() Gets the list of dates in this collection.
List<TDerivative>	getFirstDerivatives() Gets the list of first derivatives in the collection.
List<Motion2<T,TDerivative>>	getMotions() Gets the list of motion instances in this collection.
int	getOrder() Gets the number of derivatives in this collection.
List<TDerivative>	getSecondDerivatives() Gets the list of second derivatives in the collection.
List<T>	getValues() Gets the list of values in the collection.

Method Detail

getCount

public final int getCount()

Gets the number of items in this collection.

getOrder

public final int getOrder()

Gets the number of derivatives in this collection.

getDates

public final List<JulianDate> getDates()

Gets the list of dates in this collection.

getMotions

public final List<Motion2<T,TDerivative>> getMotions()

Gets the list of motion instances in this collection. Consider using Values (get), FirstDerivatives (get), SecondDerivatives (get), etc. to get all the corresponding data as a single list. This is more efficient than requesting a list of motion instances.

get

public final List<TDerivative> get(int index)

Gets the list of the specified derivative.

Specifying an index of 1 retrieves a list of all first derivatives. Specifying 2 retrieves a list of all second derivatives. And so on.

Parameters:

index - The derivative list of retrieve.

Returns:

The requested list.

getValues

public final List<T> getValues()

Gets the list of values in the collection.

getFirstDerivatives

public final List<TDerivative> getFirstDerivatives()

Gets the list of first derivatives in the collection.

getSecondDerivatives

public final List<TDerivative> getSecondDerivatives()

Gets the list of second derivatives in the collection.
